I posted this some time ago and thought it would be a neat strain to kick off the new category. This one is unembossed. From my research I find it is used at the apex of the inverted V antenna. A metal slotted bracket would be at the apex. The hooked end would be placed in the slot and turned so as not to fall out. The antenna wire would then be connected to the end with the eye. This type of antenna would utilize two of these at the apex. This is what I refer to as a GS-036. GS being glass strain. About 4-1/4 inches in length.
